Device Information

The high saturation level must be between 20.5 mA and the high alarm value
minus 0.1 mA.
Example: The high alarm value has been set to 20.8 mA. Therefore, the low
saturation level, S, must be as follows:
20.5 ≤ S ≤ 20.7 mA.
Preset alarms can either be 1 Rosemount or 2 NAMUR-compliant. Use the
failure mode switch on the front side of the electronics (see "Switch Location"
on page A-7) to set whether the output will be driven to high or low alarm in
the case of failure.

HART Output

HART Fast Keys 1, 3, 4, 3
The HART Output command allows the user to make changes to the
multidrop address, initiate burst mode, or make changes to the burst options.

LCD Meter Options

HART Fast Keys 1, 3, 4, 4
The LCD Meter Option command sets the meter options, including
engineering units and decimal point. Change the LCD meter settings to reflect
necessary configuration parameters when adding a LCD meter or
reconfiguring the transmitter. Transmitters without LCD meters are shipped
with the meter configuration set to "Not Used."
To customize variables that the LCD meter displays, follow the steps below:
1. From the home screen select 1 Device Setup, 3 Configuration, 4 Dev
Output Config, 4 LCD Meter Options, and 1 Meter Config.
2. Select the appropriate variable configuration from the Meter
Configuration screen.
3. Press F4, ENTER, and then F2, SEND, to send the information to the
transmitter. The LCD meter will scroll through the outputs selected in
step 2.
To change the decimal point configuration, perform the following steps:
1. From the home screen select 1 Device Setup, 3 Configuration, 4 Dev
Output Config, 4 LCD Meter Options, and 2 Meter Decimal Pt.
2. Choose from Floating Precision or One-, Two-, Three-, or Four-Digit
Precision by pressing F4, ENTER. Press F2 to send the information to
the transmitter.
To change the meter bar graph, perform the following steps:
1. From the home screen, select 1 Device Setup, 3 Configuration, 4 Dev
Output Configuration, 4 LCD Meter options, 3 Meter bar graph.
2. Choose from Bar Graph offer, Bar graph on by pressing F4, Enter. Press
F2 to send the information to the transmitter.
Access the transmitter information variables online using the HART
Communicator or other suitable communications device. The following is a list
of transmitter information variables. These variables include device identifiers,
factory-set configuration variables, and other information. A description of
each variable, the corresponding fast key sequence, and a review of its
purposes are provided.
